Maximum overlaps of these entities are described in the limitation similarity theory. Seven models for the apportionment of these entities such as dominance decay and MacArthur fractions were ranked by Mutsunori Tokeshi to explain relative abundance distributions. (10[1])G. Evelyn Hutchinson represented these entities as n-dimensional hypervolumes. (10[2])Joseph H. Connell (10[1])proposed “ghosts (10[1])of competitions past and present” to explain these entities’ (10[1])“differentiation.” (10[1])That scientist (10[1]-5[1])also studied barnacle habitat ranges (10[2])in (-5[1])describing (-5[2])the “fundamental” and “realized” (10[1]-5[1])types (10[2])of these (10[4])entities. (10[3])The competitive exclusion (10[2])rule (10[2])that (-5[1])states two species (10[2])sharing (10[4])identical (10[2])ones of (10[1])these (10[1])entities (10[6])cannot (10[2])coexist. (10[6])For 10 points, name (10[1])these entities that describe how an organism (10[1])matches (10[1]-5[1])its (10[1])environmental factors. (10[2])■END■ (10[4]0[4])
